The Hetocumtek totem pole contained psychophonic programming. If it splintered someone, it would curse their name. This happened to Clyde Langer, with the psychophonic programming isolating Clyde so that Hetocumtek could use the boy's energy to come back to life. To break the curse, those had to keep saying Clyde's name. (TV: The Curse of Clyde Langer [+]Phil Ford, The Sarah Jane Adventures series 5 (CBBC, 2011).)
